Knowledge and self-care behavior among heart failure patients in South India.

Background: Heart failure (HF) is a chronic condition with significant public health concerns. HF necessitates adequate knowledge and adherence to self-care for enhanced quality of life and decreased rehospitalization. This study aimed to explore knowledge and self-care behavior in patients with HF.

A newly bat-borne hantavirus detected in Seba's short-tailed bats (Carollia perspicillata) in the Brazilian Atlantic Rainforest.

Background: Bat-borne hantaviruses have been identified worldwide but little is known about neotropical bats in the megadiverse biomes of the American continent. Although serological evidence has hinted at hantavirus circulation in Brazil, the scarce number of genomic detection represents a gap to understand viral diversity, prevalence, and ecology of bat-borne hantaviruses.

Objective: We aim to investigate and evaluate the presence and prevalence of bat-borne hantavirus in the Brazilian Atlantic Forest.

Challenges and lessons from the COVID-19 pandemic for Health Surveillance in Brazil: reflections on technologies, models, and system organization.

The term "health surveillance" encompasses a wide range of activities, including the monitoring and observation of harms and diseases. We will investigate the most well-known aspect of health surveillance, namely the monitoring of communicable diseases. To illustrate our discussion, we will use the pandemic caused by the SARS-CoV-2 virus as a case study.

Unraveling the Nanomechanical and Vibrational Properties of the Mayaro Virus.

Mayaro virus (MAYV) is an emerging mosquito-borne viral pathogen whose infection results in arthritogenic disease. Despite ongoing research efforts, MAYV biology is largely unknown. Physical virology can assess MAYV nanoparticle metastability, assembly/disassembly, and polymorphism, allowing us to understand virion architecture and dynamics.

Robotic endovascular peripheral arterial interventions: a proposal of a new learning model.

Objective: This study tests a suitable model for training robot-assisted peripheral vascular interventions and examines the learning curves of endovascular surgeons with different levels of previous experience and main focus of work, analyzing procedure time, fluoroscopy time, use of contrast, and radiation emission.

Methods: Sixteen endovascular surgeons with different previous experience and training performed nine manual and 18 robotic angioplasties using the CorPath GRX platform on a 3D-printed life-size immersed infragenicular arterial phantom.

Results: All participants considered the model reliable.
